FIELD OF THE INVENTION

The present disclosure relates to automatic washing machines having at a plurality of load size indicators. The present disclosure further relates to processes of treating fabric articles using such machines. The present disclosure further relates to instructional systems that include a plurality of load size indicators.

BACKGROUND OF THE INVENTION

To achieve optimal performance benefits when washing or otherwise treating laundry, the recommended dosage of fabric care treatment composition, such as a conventional detergent, is typically dependent on the size of load to be treated. Small loads require smaller amounts of a treatment composition, while larger loads require larger amounts. However, modern developments in laundry practices and technologies have removed some of the traditional cues that users have used to estimate load sizes and dosage levels, thereby leading to mis-dosing and suboptimal performance.

Changes in modern automatic washing machines have contributed to this problem. For example, traditional machines often require a user to actively select a load size before starting the machine; however, modern machines may automatically sense the size of a load, thereby removing the necessity to proactively assess load size. Consumers who grew up with top-loading washing machines may be accustomed to using the agitator and/or the inner wall of the drum of the machine as a visual yardstick when assessing laundry loads from a top-view perspective; however, front-loading machines are becoming more popular and do not offer the same visual cues. Additionally, the inner volume of laundry machines have, on average, become larger, so that a half-full machine today may actually contain a greater amount of laundry than a half-full machine of yesteryear.

Packages of fabric care treatment compositions often include graphical indicia that guide a user to use the recommended dose for a particular load size. Compared to textual instructions, graphical indicia may be easier to understand for a variety of users, such as those who do not speak or read a local language. These graphical indicia often illustrate laundry load size in terms of a traditional wide-mouthed laundry basket. However, it may be challenging for a user to properly correlate his or her actual load size to the load size (and consequent dose) shown on the graphical indicia. For example, commercially available baskets do not have a standardized volume. Additionally, modern consumers may not even use a traditional basket. Instead, they may use collapsible containers, flexible bags, or taller baskets with a smaller footprint, as such containers may be preferred for space, cost, and/or aesthetic reasons.

Finally, modern forms of fabric care compositions may contribute to dosing problems as well. For example, water-soluble pouches that encapsulate fabric care compositions offer the no-mess convenience of a pre-measured unitized dose. However, the dosing options offered by such pouches are digital—a consumer can add one, two, three, etc., pouches—and do not allow for intermediate volumes, whereas a consumer who used a traditional liquid detergent with a dosing cap could add a little more or a little less than the recommended dose of detergent, depending on his/her assessment of the load size. Furthermore, a user may be uncertain as to whether he or she is “allowed” to use more than one pouch for a load, particular in modern high-efficiency washing machines, which employ lower water volumes than traditional machines.

Given the challenges above, there is a need for systems and methods that improve a user's ability to assess laundry load size and provide the appropriate dosage of a fabric care composition.

DETAILED DESCRIPTION OF THE INVENTION

The subject matter of the present disclosure improves a user's ability to assess laundry load size by providing load size indicators on an automatic fabric washing machine in close proximity to fabric articles once the articles are loaded into the machine. Because the load size indicators are directly on the machine, a user can quickly, accurately, and consistently assess the load size, removing some guess-work. Such assessment of load size is thereby decoupled from a user's laundry basket (if any), a common reference point on instructional labels.

Additionally, the indicators may further include dosing indicia that indicate a fabric care composition dosage amount that is appropriate for a given load size. After a user has placed fabric articles into the drum of the machine, the user can compare the amount of the articles to the nearest load size indicator and readily determine the proper dosage amount for that particular load size. Using the proper amount of fabric care composition may ensure that a sufficient amount of the composition is used to effectively treat the fabric load without over-dosing the composition.

The second load size indicator 300 also includes a dosing indicia 320, illustrated in FIG. 3 as two unitized dose articles 324. The elements of the load size indicators 200, 300, 400 are discussed in more detail below, and exemplary embodiments are shown in FIGS. 4-11 on various washing machines 101, 102.

The load size indicators 200, 300, 400 may include a visual or tactile indication to a user of a first load size of fabric articles when such articles are placed in the interior volume of the drum.

At least one load size indicator 200, 300, 400 may provide a visual indication. At least one of the first and second load size indicators may include a line 212, an arrow 213, a color 214, a textual indicia, or combinations thereof.

At least one of the load size indicators 200, 300, 400 may include a line 212. The line 212 may be a segment having a first end and a second end. The line 212 may form a closed shape. For example, the line 212 may be located on a drum wall 116 and may encircle the drum 110, going all the way around.

At least one of the load size indicators 200, 300, 400 may include a color 214. The first load size indicator 200 may include a first color 214, and the second load size indicator 300 may include a second color 314. The second color 314 may be different than the first color 214, so that the first and second load size indicators 200, 300 may be more easily distinguishable.

At least one of the load size indicators 200, 300, 400 may include textual indicia. For example, the indicia may display text that signals a relative load size, such as “M” or “MEDIUM” and/or “L” or “LARGE” and/or even “XL” or “EXTRA LARGE.”

At least one of the load size indicators 200, 300, 400 may provide a tactile indication. At least one of the indicators 200, 300, 400 may include a raised surface and/or a lowered surface compared to an adjacent surface. The adjacent surface may be integral part of the automatic washing machine 100.

The load size indicators 200, 300, 400 may further include dosing indicia 220, 320, 420. The dosing indicia 220, 320, 420 may indicate an appropriate dose of a fabric care composition based on a predetermined estimate of a load size. The predetermined estimate of a load size may be based on any suitable amount of fabric articles 600. The estimate of load size may be based on an estimate of the absolute amount of fabric articles 600 in a given load. For example, the load size may be from about 1 kg to about 12 kg, or from about 2 kg to about 5 kg of fabric articles. The estimate of load size may relate to a feature of the machine. For example, the load size may be a fraction of the interior volume 118 of the drum 110, such as from about 1% to about 100% of the interior volume 118. The first load size of fabric articles 600 may be a first fraction of the interior volume 118, where the first fraction is from about 5% to about 50% of the interior volume. The second load size of fabric articles may be a second fraction of the interior volume 118, where the second fraction is from about 30%, or from about 50%, to about 100%, or up to about 75% of the interior volume 118. The second fraction may be greater than the first fraction.

A first load size indicator 200 may include a first dosing indicia 220, which may indicate a first appropriate dose of a fabric care composition based on a first predetermined estimate of load size. A second load size indicator 300 may include a second dosing indicia 320, which may indicate a second appropriate dose of a fabric care composition based on a second predetermined estimate of load size.

The first and second dosing indicia 220, 320 may be different from each other. The first and second dosing indicia 220, 320 may be located apart from each other. The dosing indicia 220, 320 may be located proximate to the visual or tactile indication 210, 310.

The dosing indicia 220, 320 indicate an appropriate dose of a fabric care composition. An appropriate dose may be any dose of a fabric care composition that is suitable for the estimated load size. The dosing indicia 220, 320 may indicate doses as amounts of unitized dose articles 224, 324, such as water-soluble pouches. A first dosing indicia 220 may indicate a first amount of unitized dose articles 224, such as one. A second dosing indicia 320 may indicate a second amount of unitized dose articles 324, such as two. The appropriate doses may also be represented as volumes 226, 326, 426, such as volumes of a dosing cup 228, 328, 428. A first volume 226 may be different than a second volume 326. The appropriate doses may include one dosing form, such as unitized dose articles 224, 324, 424 or volumes 226, 326, 426 of a dosing cup 228, 328, 428, or multiple dosing forms, such as both. The dosing indicia 220, 320 may be associated with or labeled as a particular brand of a fabric care composition, such as TIDE, GAIN, and/or ARIEL, available from The Procter & Gamble Company, Cincinnati, Ohio, USA.

The automatic fabric washing machine 100 may further include a third load size indicator 400 disposed on or adjacent the drum 110 and providing a visual or tactile indication 410 to a user of a third load size of fabric articles 600 when such articles 600 are placed in the interior volume 118 of the drum 110. The third load size indicator 400 may further include at least a third dosing indicia 420 that indicates a third appropriate dose of a fabric care composition based on a predetermined estimate of load size. The third dosing indicia 420 may be different from the first and second dosing indicia 220, 320. The third dosing indicia 420 may be located separately from the first and second dosing indicia 220, 320.

The load size indicators 200, 300, 400 may be located on or in an automatic fabric washing machine 100. The load size indicator may be affixed to the machine 100, for example in the form of a sticker, or the indicators may be formed integrally with the material of the machine 100.

Process of Treating Fabric Articles

The present disclosure also relates to a process of treating fabric articles. More specifically, the process relates to using the load size indicators described herein to determine a load size of fabric articles and an appropriate dose of a fabric care composition for that load size, and then providing that appropriate dose to the articles.

The process may include providing an automatic fabric washing machine 100 as described herein. The machine 100 may have a drum 110 with a closed end 112, an open end 114, a drum wall 116, and an interior volume 118. The automatic fabric washing machine 100 may be an automatic top-loading washing machine 101 or an automatic front-loading washing machine 102.

The automatic fabric washing machine 100 may include load size indicators 200, 300, 400 as described herein. The machine 100 may include at least a first load size indicator 200 and a second load size indicator 300. The machine may further include a third load size indicator 400 as described herein.

The load size indicators 200, 300, 400 may be disposed on or adjacent a drum 110 of an automatic washing machine 100. At least one or more of the load size indicators 200, 300, 400 may be disposed at any suitable location on the automatic washing machine 100. The location may be selected from the group consisting of a door 130, a rim 120 proximal to the open end 114 of the drum 110, a window 136, a drum wall 116, an agitator 140, or a combination thereof.

The first load size indicator 200 may be disposed on or adjacent a drum 110 and provide a visual or tactile indication 210 to a user of a first load size of fabric articles 600 when such articles 600 are placed into the interior volume 118 of a drum. The first load size indicator 200 may further include at least a first dosing indicia 220, where the first dosing indicia 220 indicates a first appropriate dose of a fabric care composition based on a first predetermined estimate of load size.

The second load size indicator 300 may be disposed on or adjacent a drum 110 and provide a visual or tactile indication 310 to a user of a second load size of fabric articles 600 when such articles 600 are placed into the interior volume 118 of a drum 110. The second load size indicator 300 may further include at least a second dosing indicia 320, where the second dosing indicia 320 indicates a second appropriate dose of a fabric care composition based on a second predetermined estimate of load size.

The first and second indicia 220, 320 may be different from each other. The first and second indicia 220, 320 may be located apart from each other.

The machine may include a third load size indicator 400, as described herein.

The process may further include providing fabric articles 600 to the interior volume 118 of the drum. The fabric articles 600 may be characterized by a provided load size, measured in any suitable manner, such as by weight, by volume, or by fraction of a feature of the automatic fabric washing machine 100.

The process may further include determining a matched load size indicator. The matched load size indicator may be selected from at least the first and second load size indicators 200, 300. The matched load size indicator is determined by comparing the provided load size of fabric articles to the load size indicators (e.g., the first and/or the second load size indicators 200, 300) and determining which load size indicated by the visual or tactile indication 210, 310 more closely approximates the provided load size.

Once the matched load sized indicator is determined, a user may observe the dosing indicia to determine what dose is appropriate for the provided load size. For example, when the provided load size is up to 3 kg, or up to about 4.5 kg, or a first fraction (such as approximately up to about one-third, or up to about half) of the interior volume 118 of the drum, the appropriate dose may be one unitized dose article. When the provided load size is from about 3 kg, or from about 4.5 kg, up to about 7 kg, or a second fraction (such as approximately from about one-third, or from about half to about two-thirds, or to about three-quarters) of the interior volume 118 of the drum, the appropriate dose may be at least two or more unitized dose articles.

The process may further include providing to the fabric articles 600 the appropriate dose of a fabric care composition as indicated by the dosing indicia of the matched load size indicator.

The process may further include starting a treatment cycle of the automatic fabric washing machine. The treatment cycle may include washing, soaking, rinsing, draining, or a combination thereof. At the end of the treatment cycle, the fabric articles may be dried.

In FIG. 11, a front-loading washing machine 102 is shown, where fabric articles 600 have been placed into the drum 110. The load size indicators 200, 300, 400 are disposed adjacent the drum 100, specifically located at the rim 120 of the drum 100. The visual indications 210, 310, 410, include first, second, and third colors 214, 314, 314. The dosing indicia 220, 320, 420 use representations of unitized dose articles 224, 324, 424 to show appropriate dosage amounts for different load sizes. In FIG. 11, the provided load size of fabric articles 600 most closely aligns with the second load size indicator 300, which is coupled with a dosing indicia 310 showing that two unitized dose articles 324 is an appropriate dosage amount for the given load size. A user, then, may add two such articles to the drum 110 of the machine 102 and start the wash cycle.

Instructional System

The present disclosure also relates to instructional systems 500 that include load size indicators as described herein. The instructional systems 500 may be designed to be affixed to an automatic fabric washing machine 100 as described herein.

As illustrated in FIG. 12, the instructional system 500 may include a substrate 510. The substrate 510 may have a printed side 520. The substrate 510 may have an application side 530 opposite the printed side 520. The instructional system 520 may be in the form of a sticker or a magnet.

Suitable substrates 510 may comprise cellulosic substrates and/or plastic substrates.
